I have the boppy and the my brest friend pillow, and I like both for different purposes.

I started off with the boppy, but ds was too small when first born and kept sliding into the gap between me and the pillow. So I bought the my brest friend pillow, which worked better while he was small. You have to be careful with that one though...I was always nervous he was going to roll off the thing because it's so stiff. Now that he's bigger, the boppy works better for us.
